LINER-PLATE Specification of Letters Patent.

Patented Jan. 28, 1908.

Application filed July 29. 1904. Serial No. 218.693.

.T 0 all whom it may concern:

Be it known that I, BERNHARD ADOLF Or'ro PROLLIUS, of No. Torvegade, Copenhagen, Denmark, have invented certain new and useful Improvements in Liner-Plates for Centrifugal Apparatus, of which the following is a specification.

The present invention relates to improve ments in liner-plates for centrifugal apparatus, and my improvement makes it possible to center the liner plates exactly with relation to the separators rotationaxis and to place them in absolutely correct position relatively to each other, which is a very important feature. The surfaces of the plates, are, moreover of such a form, that a uniform distribution of the milk over the entire surface of the plate is obtained.

The accompanying drawing shows one embodiment of the invention, by way of example.

Figure 1 shows a perspective view of a liner-plate; Fig. 2 is a top-view of the same; Fig. 3 is a section on line A-A, .Fig. 2, showing two adjacent plates; and Fig. 4 is a section on line BB, Fig. 2, through two plates and on an enlarged scale.

Along the interior rim of each of the plates a, a suitable number of channel shaped depressions b are formed. The form of the depressions is shown in the drawing and it will be seen that the depth of the channel decreases gradually from c to (Z, the bottom of the channel finally merging into the surface of the plate. The cross-section of the depressions is most clearly shown in Fig. 4, and it will be seen that, owing to the thickness of the material itself, the depressions will keep the plates at a certain distance from each other when the liner is arranged in such a manner, that the depressions of one plate are seated in the depressions of the adjacent plate. This arrangement also serves to keep the plates exactly in the same position with relation to the separators axis.

Between the bottoms of the depressions of adjacent plates, passages 6 (Figs. 3 and 4) are formed" and the plates may be adjusted into such a position that the passages are e outlets for the milk. By this arrangement is attained that milk will flow into the passages, and as the bottoms of the depressions 1) merge into the surface of the plate, as is stated above, the milk will be distributed evenly and uniformly over the entire surface of the plate.

Having thus described my invention, what I claim as new is:

1. A conical liner plate for centrifugal-apparatus having in its upper rim a plurality of radially directed depressions forming channels of decreasing depth open at both ends and having their bottom merging into the surface of the plate.

2. In a centrifugal apparatus a plurality of conical liner plates; each of the plates hav ing in its upper rim a plurality of radially directed depressions open towards the interior of the apparatus and forming channels of decreasing depth having their bottom merging into the surface of the plate.

3. In a centrifugal apparatus a plurality of conical liner plates; each of the plates having in its upper rim a plurality of inwardly extending channel-shaped depressions open towards the interior of the apparatus and adapted to be seated in the depressions of the adjacent lower plate; the depressions of all the plates being of uniform size so as to provide for the same amount of space between the adjacent plates and having tapering sides and a bottom merging into the surface of the plate.

4. In a centrifugal apparatus a plurality of conical liner plates; each of the plates having in its upper rim a pluralityv of channelshaped towards the interior of the apparatus and with their bottom merging into the surface of the plate and adapted to be seated in the depressions of the adjacent lower plate thereby forming passages between the bottoms of adjacent depressions through which the liquid to be separated is distributed over the liner plates.

In witness whereof I have hereunto set my hand in presence of two witnesses.
